Kinetika Slow-Released Pupuk Urea Terenkapsulasi Dalam Alginat

نویسندگان

چکیده

Pupuk urea merupakan komoditas yang penting di sektor pertanian. digunakan petani seringkali terbawa air sehingga pelepasannya tidak efisien. Oleh karena itu diperlukan proses enkapsulasi pupuk agar dapat dikontrol. Alginat sebagai pelapis berbagai material. Tujuan penelitian adalh untuk mengetahui diameter rata-rata hasil dengan alginate dan uji pelepasan terenkapsulasi dalam alginat air. Pada ini dilakukan pembuatan serta permodelan kinetika slow-release terenkapsulasi. Enkapsulasi menghasilkan butiran 3,01 mm. Uji masih terjadi setelah waktu 20 menit. Berdasarkan diperoleh data nilai difusivitas efektif sebesar 5,2342 x 10-10 m2/s koefisien transfer massa dari permukaan ke badan cairan 1,9684 x10-06 m/s. Urea fertilizer is an important commodity in the agricultural sector. used by farmers often carried away water so that its release inefficient. Therefore, it necessary to encapsulate can be controlled. Alginate as a coating for various materials. In this study, preparation of encapsulated and kinetics modeling was done. The produced granules with average 3.01 test still occurred after 30 minutes. Based on modeling, effective diffusivity value mass coefficient from surface liquid 10-06

Toward surgical angiogenesis using slow-released basic fibroblast growth factor.

OBJECTIVE Therapeutic angiogenesis using basic fibroblast growth factor (bFGF) in coronary artery disease has been documented in a number of papers. However, the effectiveness is discrepant among documents. In this study, we evaluated the distribution of bFGF in the rat heart by different administration methods, and investigated the efficacy of slow-released administration of bFGF using biodegr...

A green slow-release fertilizer composition based on urea-modified hydroxyapatite nanoparticles encapsulated wood

In this paper we describe a strategy for sustained release of nitrogen into the soil. Specifically, ureamodified hydroxyapatite nanoparticles were encapsulated under pressure into cavities of the soft wood of Gliricidia sepium. Nitrogen release of the nanofertilizer composition was studied using soil from three elevations in Sri Lanka (pH 4.2, 5.2 and 7) and compared with that of a commercial f...

Effects of slow-release urea on ruminal digesta characteristics and growth performance in beef steers.

Two experiments were conducted to evaluate the effects of slow-release urea (SRU) versus feed-grade urea on ruminal metabolite characteristics in steers and DMI, gain, and G:F in growing beef steers. Experiment 1 used 12 ruminally cannulated steers (529 +/- 16 kg of BW) to monitor the behavior of SRU in the ruminal environment. Compared with feed-grade urea, SRU decreased ruminal ammonia concen...
